A simple sequence in which 13 C precessions are allowed to develop with proton coupling for a period of 1/2 3 J (CH) s before initiating decoupling and acquisition allows the determination of vicinal carbon–hydrogen coupling constants to facilitate the characterization of trisubstituted double bonds. The experiment is illustrated by studies of citraconic anhydride and limonene.
